Originally created by @leetheman on GitHub (Feb 27, 2024).

Hi, simple one to reproduce here:

  1. Create a Radzengrid, allow column picker
  2. Wire the datasource up to a List or IEnumerable
  3. Create a method to "refresh" which sets the List/Ienumerable to a new datasource (e.g. to simulate refreshing an EFCore Query)
  4. Run the project, hide some columns and click on refresh - the hidden columns will be shown.

Telerik does not have this issue but I prefer your grids.

This happens if I set my datasource to = a new data source, or an empty collection, or if even clear it (so the reference is still the same)

Please see GIF attached

Setting new data will reset everything - this is by design

OK, I don't get the logic - if it's bound to a SQL table, and records are added to that table, why should the columns be reset?

Nothing else gets reset - the sorting/filtering remains the same. So this is consistent grid state behaviour
